8.2.2.1.5. Timing
Options
Especially when using Modem Control signals it will be required to
hold them in a given state for a defined amount of time. This may be
done by applying a »Pause«-command in the “InitString”. The delay is
given as numeric value in milliseconds (msec), preceded by a ‘P’. So
<P50> causes the NetCom to wait 50 msec before proceeding with the
next command or start printing. Up to three digits are possible. If more
than 999 msec are required, the Pause-command must be repeated.
Please note: The delay is not executed as an exact time. NetCom
guarantees to wait at least the required amount of time. The smallest
delay possible is 10 msec, due to internal handling of date and time.

8.2.2.2. Reset
Example
For example here is a hypothetic serial printer. The serial port operates
at 1200 bps, 7 bit and even parity and 1 stop bit. For Reset the printer
requires the command “<ESC>@0” sent with DTR and RTS off. When
the data is transmitted, DTR must be on, and 50 msec later RTS must
also be on.
Each character sent is 10 bits long, including the start bit. At 1200 bps
each character needs 8.3 msec for transmission. So the transmission
lasts for 25 msec. To be sure the control signals are active, an extra
delay is applied after change of signals. The resulting string would be
at 1200 bps, 7 bit and even parity and 1 stop bit. For Reset the printer
requires the command “<ESC>@0” sent with DTR and RTS off. When
the data is transmitted, DTR must be on, and 50 msec later RTS must
also be on.

<RTS-><DTR-><P10><ESC>@0<P35><RTS+><P50><DTR+>
The delay of 35 msec after the command data shall ensure, all data is
completely transmitted to the printer.

The Printer Server mode may be used to support serial printers in
Windows® Operating System. This is a short instruction how to install
and use it. Experience on installing printers in Windows is required for
this instruction. First the installation of a new printer is given, the
modification of an existing printer setup is described later.
